Abstract
We have observed surface-molecule electron transfer from the semiconductor diamond (111) surface to the iodine molecule, following hyperthermal molecular-beam scattering. The negative-ion mass spectrum was dominated by undissociated molecular ions. No positive ions were observed. The threshold kinetic energy was ≅ 3 eV and an absolute yield of ≅ 1% was measured at 10-eV incident kinetic energy. The surface temperature effect on the yield was small. The ions' energy distribution was broad and the angular distribution was shifted towards the surface.This publication has 28 references indexed in Scilit:
